GEORGE W. ELLIS, OF PHILADELPHIA, PENNSYLVANIA.

TRUSS.

SPECIFICATION forming part of Letters Patent No. 245,467, dated August 9, 1881.

Application filed May 24, 1881.

To all whom it may concern Be it known that 1, GEORGE W. ELLIs, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Truss; and I do hereby declare that the following is a full, clear, and exact description of the same.

I have received Letters Patent of the United States, No. 222,579, for a truss for reducing hernia, in which the pad is attached to the spring by means of a metal bar havinga spheri cal head that is confined between two clamping plates or jaws, forming a permanent and rigid attachment of the spring.

My present invention is an improvement upon such device, and I will proceed to describe its construction and operation by reference to accompanying drawings, in which- Figure l is a front view, and Fig 2 a top or edge view, of my improved truss, save the body-straps and a portion of the spring. Fig. 3 represents, detached from each other, the several parts constituting the adjustable connection between the pad and spring. Fig. 4. is an inner side view of the pad-bar and socketdisk connected, as required, for use. Fig. 5 is a front view of the slotted plate attached to the truss-spring. Fig.6 is a horizontal sec-' tion on line 00 m, Fig. 1.

The spring A is provided with the ordinary leather sheath and body-strap. The pad B is attached to a forked bar, 0, which has a spherical head, a, that enters a socket formed by and between the circular steel disks D E, which are rigidly connected by screws 1 2 3, and form an attachment of the spring A, or of a plate, F, secured to the latter. To form the said socket the diskD is provided with a countersunk hole in its inner side, and the inner disk, E, has a central conical or hood-shaped projection, I), which is notched on one side to accommodate the shank of the pad-holding bar 0, and allow adjustment of the same to enable the pad to be placed at various angles. The spherical head a of the bar 0 is thus (No model.)

confined in a socket of corresponding shape, and it is clamped to hold the pad in any required position by means of a thumb-screw, G, which passes through the tubular pivot of the disk and bears directly on said head, as shown in Fig.6. To assist in holding the head of bar 0 the bottom of the socket b is provided with short teeth, as shown in Fig. 3. The pivot 0 passes through the center of the circular head of plate F, and is upset so as to secure the two parts D E together, and yet allow the disk to rotate freely to permit the pad A to be shifted vertically. The clamp-screw d serves to hold the pad fixed in any vertical adjustment, the same passing through an areshaped slot in the head of plate F and entering the disk D.

By means of the two disks D E and the thumb-screw, constructed and connected in the particular manner shown and described, I form a very compact, secure, serviceable, and easily and quickly adjustable clamp, by which the pad-bar O is held at any required angle.

I do not claim the screw and are slot, they having long been employed for substantially the same purpose as in this instance; nor do I claim, broadly, the application of a screwclamp for securing a pad-holding bar in different adjustments.

What I do claim is- The combination, with the pad-holding bar having a spherical head, and the plate F, having a central aperture, of the disks D E,which are rigidly connected so as to rotate together, one ofsaid disks having a hollow tapped pivotpost, and the other a notched and toothed socket, as specified, and the thumb-screw,which enters said post an d bears directly on the head of the bar, all as shown and described, to operate as specified.
